When in LFR, every boss in MSV has a random chance to drop one when you kill it the first time that week. Sigil of Wisdom from HoF. I am not sure what Terrace drops.

Same thing in normal and heroics only its works for the whole group rather then one person. So if it drops, everyone in the group gets one.

The generalist looks outward; he looks for living principles, knowing full well that such principles change, that they develop. It is to the characteristics of change itself that the mentat-generalist must look. There can be no permanent catalogue of such change, no handbook or manual. You must look at it with as few preconceptions as possible, asking yourself, "Now what is this thing doing?"-Children of Dune

From my experience doing LFR on 2 toons and my brother doing it on 2 toons, it tends to average out at about 1 sigil per week for each part of MSV. So 2 per week if you do both parts. You're looking at 4-8 weeks to get all 10 sigils if you only do LFR. At the moment, I'm sitting on 12 of the things on one of my toons as is my brother. I'm not geared enough for HoF so can't get the second sigil yet. Gear RNG really hates me.

RNG for the sigils can be bad, though. I've had weeks where I got none and a weeek where I got 5. Since you have to get the wisdom sigil from HoF and get honored with Black Prince, there's no reason to really hurry to get the sigils. If I had my sha-touched weapon sitting in my hot little hands, then I'd be more inclined to be impatient for my sigils. Rep is easy enough to farm. At that point, doing LFR and normal MSV/HoF is really the best option if you want sigils fast.

Got the Terrace 2hand today (LFR version though) but still missing out on Wisdom : / And as I quit raiding (my guild disbanded, and I'm lazy..), I only got LFR and the rare good PuG to rely on.. Can take some time :P

But yeah, Power/Wisdom got a random drop rate, Power is from MSV and Wisdom is from HoF/Terrace (Maybe Power drops in Terrace aswell? I realy dont know)

It's all about luck. Though I'd say more chance to get a sigil than an item off a boss.
